Extracting longitudinal shower development information from crystal calorimetry plus tracking
نویسنده
چکیده
We propose a novel approach to derive longitudinal shower development information from a longitudinally unsegmented calorimeter such as the BABAR electromagnetic calorimeter by utilizing tracking information in conjunction with that of calorimetry. We show that using this information as part of an electron identification algorithm results in a significant reduction in the pion misidentification probability for low momentum particles. We also demonstrate how this information provides general charged particle separation at low momentum, particularly between pions and muons.

The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter uses a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behavior is obtained. The underlying radial energy densities for fo...
